Any sustained temperatures above 30°C will indeed kill the temperate species - not sure about the Mexicans though. I've been experimenting for several years now in a hot summer climate and these are the results so far:

Failed:

x ventricosum
Ulla Silkens
macranthos
yatabeanum

Some success:

parviflorum
japonicum
debile
formosanum
kentuckiense

I live on the island of Kyushu, southernmost of the main Japanese islands. The climate is warm temperate, but we are close to the subtropics. Winters are mild, spring is warm, there is an intense monsoon season in June/July, followed by an intensely hot summer, and a long, warm fall. The overall temperature regime is very similar to Atlanta, Georgia, USA, but the climate is quite different. Not a good place to grow Cyps, but I am a madman.

Good luck. Start with just a few and experiment. I recommend a soil-less, organic free mix or you will have rot problems.
